Application filed May 15, 1897. Serial lia1 636,791. (No model.)Patented in France November 19,1896,1lo.261,415; in Belginm February9,1897,No1128,2`70; in Luxemburg February 9,1897,No.2,753, and inEnglandApril 6, 1897, No. 8,759.

To (LZZ whom it may concern:

Be it known that I, DANIEL MEYER, a citizen of the Republic ofSwitzerland, residing at Paris, in the Republic of France, have iuventedcertain new and useful Improvements in Incandescent Gas-Burners, (forwhich I have obtained patents in France, No. 261,415, dated November 19,1896; in Belgium, No. 126,270, dated February 9, 1897; in Luxemburg, No.2,753, dated February 9, 1897, and in England, No. 8,759, dated April 6,1897 and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others Skilledin the art to which it appertains to make and use the same.

This invention has for its object an improved burner for incandescentlamps,which consists more particularly in a novel method of constructionand arrangement of the incandescent mantle, in which strings of beadsmade of material capable of the required incandescence are used, suchmantles not being liable to breakage, as in the mantles ordinarily used.

By the mixture of suitable chemical substances of the well-known kinds acompact incandescent material is obtained, Which is dried and hardenedand formed into particles of any suitable shape, such as spheres, cubes,

cylinders, pyramids, orin cluster-s or bun ches,

like grapes, tulips, and the like, of any suitable dimensions from aboutone millimeter. The particles of grains thus produced are traversedcentrally or at one side by one or more metallic or other suitable wiresor threads, by which strings or rows of them are formed. The severalstrings or rows may be combined either one above the other or side bysidethat is to say, horizontally or vertically-to form the mantle, crthe incandescent grains may be arranged in zigzag form, alternatesquares, or the like, or in some cases the metallic or other wiresconnecting them may be omitted, the grains being then connected orattached together by suitable means before being finally mounted uponthe burner.

The accompanying drawings are in illustration of my invention.

Figure 1 represents a vertical section of a burner provided with anincandescent mantle and embodying my invention. Fig. 2 represents across-section on the line 1 l, looking downward. Fig. 3 represents adetail view, in rear elevation, of the support for the said mantle andits' attaching devices; and Fig. 4 represents a vertical section throughone side of the mantle and a part of its ring and support.

Around a metal ring a are arranged a number-twelve, forinstance-of hooksZ) at equal distances apart, and upon this ring a is also provided abracket c, in which a stem d, carrying a ring or top c, is fixed at therequired height by ascrew. The rows or strings f consist each of nine(in the drawings) beads or particles of the incandescent material, fiverows of larger ones and four rows of smaller ones being shown, threadedupon a double wire of metal or other suitable material forming aloop atone end g, Fig. 4. To form the mantle the loops g are iitted over thehools b, and the other ends of the wire are then fastened around theupper ring e.

The gallery h is supported directly upon the shoulder z' of the Bunsenburner, Which is provided at the part below the gallery With fouropenings j, which I make as high as possible instead of the limitedheight ordinarily used. These openings are fitted inside withWire-gauze, and in the lower part of the Bunsen burner is screwed agas-jet communicating with the gas-supply pipe and pierced with fivesmall holes for the passage of the gas. The obj ect of this arrangementis to allow the admission to the burner of a much larger volume of airthan is the case in ordinary burners of the kind.

The burner thus made is much stronger and more durable than allheretofcre-existing forms ofincandescent burners. Moreove r, it Wearsaway much less easily and may be used for many'years without requiringany repair. It can be readily carried Without injury and it can beeasily used and lighted in the ordinary way.

Having now particularly described and ascertained the nature of my saidinr'ention and in what manner the same is to be performed, I declarethat what I claim is- 1. An incandescent mantle for a burner consistingof a number of wircs arranged in IOG lIC)

the form of a frustmn of a oone and a series of perforated beads strungon each of the wires, in combination With a burner having slot jextending nearly its Whole length sub stantially as set forth. 4

2. An ineandescent mantie for a burner, consisting of a number of Wiresarranged in the form of a frustnm of a cone and a series of perforatedbeads strong on each of the Wires snbstantially as set forth.

3. An inoandeseent inantie for a burner, consisting of a number of Wiresarranged in tubnlar form and a series of perforated beads strnng on eachof the Wires substantially as set forth.

4. An incandescent mantle in the form of a fustrum of a cone consistingof a number DANIEL MEYER. VVitnesses:
